I have an odd situation. I've been using an iPhone 5 and 6 to connect to, and test against, both an nRF51 (redbear nano) and the same code built for nRF52. It works fine.
Today I provisioned an iPhone 7, with the latest version of ios of course.
And my app works perfectly fine with the nRF51, but it is completely unable to talk with the nRF52.
When I explore using nRF Connect on the iPhone 7, as you'd expect I can see everything perfectly when looking at the nRF51.
But when I explore the nRF52 using nRF Connect, and tap the advertised device, something different happens. On the Service screen, it says "Connected", however there are zero advertised services listed. It is truly bizarre.
Using wireshark I've done a capture - see response.
I am not an expert at on-wire analysis or even wireshark, so I'm hoping that you might be able to suggest what I do to take next steps to debug.
Your thoughts would be appreciated; thanks.
